Title:
FINGERPRINT RECOGNITION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/079912
Kind Code:
A1
Abstract:
A fingerprint recognition system is provided. The system includes : at least one touch pad formed on a circuit board; a covering plate which includes a touch region, wherein when the touch region is touched by a finger, capacitance of the at least one touch pad to ground changes, and when the whole touch region is touched by the finger, the capacitance of the at least one touch pad to ground meets a preset requirement; and a processor, configured to : when the capacitance of the at least one touch pad to ground meets the preset requirement, activate a fingerprint recognition function of the fingerprint recognition system. The fingerprint recognition system may have an enough space for accommodating the touch pad, relatively high sensitivity, and reduced power consumption, and may be easily modified in development processes.
